Answer 2

I have found a solution mentioned here

I got this problem in Android Studio 4.0 when I did a Gradle sync. I fixed it by doing the following:

1. Open top-level build.gradle and change the gradle classpath to:

   classpath 'com.android.tools.build:gradle:4.0.0'
   

2. Open gradle\wrapper\gradle-wrapper.properties and change the distribution URL to:

   distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip
   

3. Copy in .idea\jarRepositories.xml from a new project

Here's my new flutter project jarRepositories.xml, you can get your own.

<?xml version="1.0" encoding="UTF-8"?>
<project version="4">
  <component name="RemoteRepositoriesConfiguration">
    <remote-repository>
      <option name="id" value="central" />
      <option name="name" value="Maven Central repository" />
      <option name="url" value="https://repo1.maven.org/maven2" />
    </remote-repository>
    <remote-repository>
      <option name="id" value="jboss.community" />
      <option name="name" value="JBoss Community repository" />
      <option name="url" value="https://repository.jboss.org/nexus/content/repositories/public/" />
    </remote-repository>
    <remote-repository>
      <option name="id" value="BintrayJCenter15" />
      <option name="name" value="BintrayJCenter15" />
      <option name="url" value="https://jcenter.bintray.com/" />
    </remote-repository>
    <remote-repository>
      <option name="id" value="Google17" />
      <option name="name" value="Google17" />

    </remote-repository>
    <remote-repository>
      <option name="id" value="maven2" />
      <option name="name" value="maven2" />
      <option name="url" value="https://storage.googleapis.com/download.flutter.io" />
    </remote-repository>
    <remote-repository>
      <option name="id" value="maven5" />
      <option name="name" value="maven5" />
      <option name="url" value="https://google.bintray.com/exoplayer/" />

    <remote-repository>

      <option name="name" value="MavenLocal" />
      <option name="url" value="file:$USER_HOME$/.m2/repository" />
    </remote-repository>
  </component>
</project>

No idea how or why, but it worked for me

Answer 3

The problem is related to the version. Try changing the version of the plugin. This worked for me.

https://developer.android.com/studio/releases/gradle-plugin?authuser=1&hl=pt-br#updating-gradle

Example:

distributionUrl=https\://services.gradle.org/distributions/gradle-6.7-all.zip

classpath 'com.android.tools.build:gradle:3.6.4'

Answer 4

The Android Gradle LintPerVariantTask now appears to be adding JARs from all build variants to its inputs: https://android.googlesource.com/platform/tools/base/+/1f9787310d64a66370627a2aaefa1e616565c17d

The libapp.so libraries containing the app's compiled Dart code are packaged in a JAR, and a different JAR is generated for each variant. I'm not sure how dynamically generated per-variant JARs are supposed to be handled if the lint task expects all variants' JARs to be available.

As a hack workaround you could change the lintOptions in app/build.gradle to disable the lint task:

lintOptions {
    checkReleaseBuilds false
}

Answer 5

Running these two commands worked for me:

flutter build apk --profile
flutter build apk --release

Answer 6

The only solution that worked for me was downgrading the gradle.build from

dependencies {
    classpath 'com.android.tools.build:gradle:4.0.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

to

 dependencies {
    classpath 'com.android.tools.build:gradle:3.5.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

and changed the gradle-warpper.properties from

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

to

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.2-all.zip

Here you can see why you should not just add lintOptions { checkReleaseBuilds false } on the gradle.
